Why choose between a wireless speaker or a docking system? With the Bowers & Wilkins Z2 AirPlay Speaker System ($400), you don't have to. A fresh take on the Zeppelin Mini, the Z2 features a top-mounted Lighting dock that fits iPhones and iPods, as well as built-in Wi-Fi for AirPlay support. Other features include class D amplifiers, custom 3.5-inch drivers with fiberglass cones, a glass-reinforced ABS enclosure, a 3.5mm auxiliary input, and your choice of black or white bodies.
